Engine Cooling a nd Lubri cati on
The cooling system consists of the following
components:
•
Gear-driven centrifugal water pump
•
W ater temperature regulator which regulates the
engine coolant temperature
•
Gear-driven oil pump (gear type)
•
Oil cooler
The engine lubricating oil is supplied by a gear
type pump. The engine lubricating oil is cooled and
the engine lubricating oil is filtered. Bypass valves
provide unrestricted flow of lubrication oil to the
engine parts when oil viscosity is high. Bypass valves
can also provide unrestricted flow of lubrication oil
to the engine parts if the oil cooler should become
plugged or if the oil filter element should become
plugged.
Engine efficiency, efficiency of emission controls, and
engine performance depend on adherence to proper
operation and maintenance recommendations.
Engine performance and efficiency also depend on
the use of recommended fuels, lubrication oils, and
coolants. Refer to the Operation and Maintenance
Manual, “Maintenance Interval Schedule” for more
information on maintenance items.
